Is the old Sony Ericsson Xperia still supported?

I am having problems with my Sony Ericsson Xperia X10 Mini Pro. Are they still supported? Can't download App to save Contacts, Photos and SMS Text messages. Hence, not able to upgrade to newer phone without losing everything. Very frustrating and I am not very technical when it comes to mobiles etc. Can't access my Google Account or anything. Can use mobile purely to phone people, incoming calls and receive/send SMS Text Messages.
